Question

Solid zinc (Zn) reacts with hydrochloric acid (HCl) in a single replacement reaction to produce zinc chloride (ZnCl2) and hydrogen gas. How many moles of hydrochloric acid would be needed to react with 6.0 mol of Zn? (Show work)

Answer 1

Step-by-step explanation:

Zn + 2HCl => ZnCl2 + H2

Mole ratio of Zn : HCl = 1 : 2. Since we have 6.0mol of Zn, we should have 12.0mol of HCl.
